Chicago, in the'county of Cook and State' -ot' Illinois," have inventedImprovements in "lfiocomotives,- of specification. I This inventionconstruction"affording relative flexibility of the*supporting"wheelsand-axles so to" readily follow uneven track. 1 f

In locomotives ofthe usual type; the

axles*are sup'por'ted'in suitable axle boxes ""mounted' on verticallydisposed guides on' the locomotive frame and having'springs interposed'between each axle box andthe frame;

Such a construction allows theend of the axle to move vertically-a.limited distance dependin upon'the resiliency of the springs, In. thepresent invention,- I provide means at: fording greater fiexibilityotmovement of the axlecoinprisingan equalizing device i n. which theopposite ends of a single axle are each connected to a longitudinallydisposed bar pivotally 1 mounted on the frame and movable in a verticalplane. The free ends of these bars are connected by suitable links to atorsion bar extending transversely of Q the frame and pivoted thereon.By means of this arrangement the axle is permitted to swing in avertical plane independent of the resiliency of the springs.

The invention consists in the combination,

construction and arrangement of parts as will hereinafter be described 1in connection with the accompanying drawings and, more particularlydefined in the appended claims. In the drawings, a Figure 1 is afragmentary top plan view of a locomotive showing one of the axlesthereof provided with an equalizing device con structed in accordancewith my invention.

. Fig. 2 is a side view of a locomotive with portionsof the supportingwheel-and one side of the frame broken away to show the construction andarrangement of the equal izing device, 1

In the drawings, one. embodiment of my invention is illustrated, asapplied to a 1000- motive frame having side plates 2, 2, an axle 3 andsupporting wheels 4;, 4. Suitable j ournal boxes 5, 5, are mountedadjacent opposite ends of the axles and are movable yer- Wmnmivt' 'WJSLoA-Nn, a citizen ofthe United States, residing at.

which the following is a "relates "to improve ments in locomotives ortrucksand hasfor its pr nclp-al ob ect to provide an improved anysuitable construction; The. equalizing.

device comprises a. pair of longitudinally disposed supporting bars 8and 9 pivotally no I l u ntcd on opposite sidesof the 'locomotive' frameon pivotal joints 8? and 9 respectiveshow'n. tiprings 10, 10, whichma'ybe ofthe usual helical type or its equivalent, are'interposed betweeneach or the axle boxes .5, 5,

I ly. {One of the'supporting bars 8 is prefen. i

ably shorterthan the 'supportin g bar 9 "as f and stirrups 8 and'9located 'ir termediate I the ends of supportingbars' Sand 9respect1-vely Tn th-epreferred form shown, each of said st1rrupsPlOjBClZS downwardly and,

outwardly into supportingfposition above its respectivespringl'tl, whichis movably mounted between the {guide plates 6, of the pedestal '7 asalready described] This ar:

' magement, ofl'the stirrup's and springs gmay bevaried,'asdesired,"*depending upon the i type of springs employec'h-andvariations in design of the frame andaxl'e. The free ends of supportingbars 8 and 9 are operatively connected by means; of a transversely dis-POSQtltOISlOIL bar 11. The supporting bar 8, which is the shorterofthe'two supporting bars, is connected tov a crank arm 12 by means of apivotal link-13. Said arm 12is rigidly mounted on i the'torsion bar '11and extends longitudinally therefrom toward the axle 3 An arm 14: isrigidly mounted on the oposite end of the torsion member 11 and extendslongitudinally in a direction opposed to the arm 12. "Arm 9 is pivotallyconnected to the arm- 14 by a pivotal link 15. The arrangement is suchthat i any: pivotal movement of one of the supporting arms such as thearm 8,.in one direction will cause rotation of the torsion member 11 anda" corresponding movement of arm 9 in the opposite direction. Anyverticaldisplacement of one end of the axle willtherefore causecorresponding displacement of the oppo-' site end of the axle in areversedirection, It will thus be seen that when the locomotive ismoving over uneven track, the axle is free to swing a limited distancein a transverse plane irrespective of theresiliencyot the springs.

In applying my invention to a locomotive of the two axle type, it ispreferable to mount one of the axles in the usual manner,

that is to say, without an equalizing device,

' wide range of flexibility with respect to the frame and the onestabilizing axle connected therewith. By means of'this arrangement, theload is maintained evenly on all of the supporting wheels while movingover uneven track. In a similar manner, when applied to a three axlelocomotive, two 'of the axles only are provided with transverseequalizing devices.

Although I have shown and described one form in which my invention maybe embodied, it will be understood that many other means may be employedfor accomplishing the same results, without departing from the spiritand scope of my invention. I do not therefore wish to be understood aslimiting myself to the specific construction or use illustrated hereinexcepting as specifically limited in the appended claims.

I claim as my invention:

1. In a car, aframe, an axle movable in a substantially vertical planerespective to said frame, and an equalizing device com-- prising a pairoflongitudinally extending bars each pivotally mounted on the frameadjacent opposite ends of said axle in sup porting engagement therewith,and means operatively connecting said bars together, including atransversely disposed. torsion member pivotally mounted on the frame.

2. In a car, a frame, an axle movable in a substantially vertical planerespective to said frame, and an equalizingv device comprising a pair oflongitudinally extending bars each pivotally mounted on the frameadjacent opposite ends of said axle in supporting engagement therewith,a transversely disposed torsion member pivotally mounted on the frame,and means coaoting between'e'ach of said bars and said torsion memberwhereby vertical movement of oneend of sald axle in one dlrection istrans mitted through the medium of said torsion member and said bars andcauses a corresponding movement of the other end of said ing bars eachpivotailly mounted-on the frame adjacent opposite ends of said axle insupporting engagement therewith, a transversely disposed torsion memberrotatably mounted on said frame, a longitudi nally disposed rigid arm onsaid, torsion member extending in one direction and hav-- ing operativeconnection with one of said bars, and an oppositely disposed arm havingoperative connection with the other of said bars,
